Support stored mysql procedures besides stored functions
MySQL stored procedures must be invoked by the "CALL" SQL command and not by "SELECT". Add the convention that if the procedure name starts with "CALL", then the issued SQL command is "CALL procedurename(args)". The stored procedure support in MySQL automatically brings transaction support too. Signed-off-by: Jozsef Kadlecsik <>
